...TROPICAL WAVES...

A tropical wave is along 107W/108W N of 04N, moving W at around 
10 kt. Scattered moderate convection within 180 nm of the wave. 

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... 

The monsoon trough extends from 09N84W to 14N95W to 
10N110W to 15N125W to 12N140W. Scattered moderate convection is
along and south of the monsoon trough from 04N to 13N between 80W
to 99W and from 07N to 12N between 112W to 120W.  

OFFSHORE WATERS WITHIN 250 NM OF MEXICO...

Please see the Special Features section above for more details on
Tropical Depression Karina. South to southwest swell from Karina
will continue to spread north and northeastward across the 
offshore waters of Baja California and the entrance to the Gulf 
of California through early Thu.

Weak high pressure will maintain moderate northerly winds and 
seas across the offshore waters of Baja California Norte through
Sun. Farther south, a weak trough will develop well offshore of
Cabo Corrientes. This will maintain light to gentle winds and 
slight seas through Sun. 

OFFSHORE WATERS WITHIN 250 NM OF CENTRAL AMERICA, COLOMBIA, and 
WITHIN 750 NM OF ECUADOR... 

Gentle to moderate S to SW winds persist south of the monsoon 
trough. Elsewhere, gentle winds prevail north of the monsoon 
trough. Combined seas are currently in the 4-7 ft range in a mix
of wind waves and S to SW swell, except 5 to 8 ft south of the 
equator. Seas may build S of Panama by late Thu in southerly
swell. 

REMAINDER OF THE AREA...

Please see the Special Features section above for more details on
Tropical Depression Karina. Karina will continue W and dissipate
into a trough through Sat. 

A stationary front is over the NW waters from 32N132W to beyond 
26N140W where it continues as a dissipating stationary front. 
Moderate SW winds are ahead of the front. The front will drift 
E-SE during the next couple of days before dissipating. Light to
moderate NE trades prevail across the waters north of the 
monsoon trough. Combined seas are generally 4-7 ft. A broad area
of fresh monsoonal flow prevails south of the monsoon trough 
between 105W to 110W, with seas generally 7-8 ft in this region.
This will persist through Fri.
